How to improve the tooth breaking strength of transmission mechanical gear PM sintered part powder metallurgy gear? Powder metallurgy gear is a high-tech product with less chips and no chips. Still according to the number of parts, its proportion in various machinery, automobiles, and motorcycles is far greater than that of powder metallurgy parts in other fields. Therefore, it canbe seen from the increase in the proportion of automobiles and motorcyclesin the entire powder metallurgy parts that Transmission mechanical gear PM sintered part powder metallurgy gears are in a position of rapid development in the entire powder metallurgy parts. The method of improving the tooth breaking strength of powder metallurgy gears: If powder metallurgy blanks are used to process gears, the strength will definitely be about 10% higher. Powder metallurgy gears produce tooth chipping because of the design: many gears are designed in a relatively compact manner, without considering minor problems such as overloading and heat treatment machining. Zhengzhou wear-resistant powder metallurgy gear manufacturer.

What are the advantages of powder metallurgy forming technology? Powder metallurgy gear strength requirements: Many friends want to know the powder metallurgy gear strength requirements. Powder metallurgy is to prepare metal powder or use metal powder (or a mixture of metal powder and non-metal powder) as raw materials , After forming and sintering, the process technology of manufacturing metal materials, composite materials and various types of products, then what are its advantages? Powder metallurgy forming technology is a net near forming technology, which can reduce manufacturing steps, no cutting, less Cutting, reducing processing, and reducing waste production. There is almost no waste in the forming process of various types of gears, and the utilization rate of steel resources is extremely high. China's wear-resistant powder metallurgy gear manufacturers powder metallurgy gear surface rust prevention: use anti-rust oil and anti-rust paper for anti-rust treatment.

Application of powder metallurgy gear types: Powder metallurgy gears are powder metallurgy parts commonly used in various automobile engines. Through one-time forming and finishing process, no other post-processing process is required, and the dimensional accuracy requirements, especially the tooth profile accuracy, can be fully met. Therefore, compared with the traditional mechanical processing method, the material input and manufacturing are greatly reduced, and it is a typical product that reflects the characteristics of powder metallurgy. Supporting examples of powder metallurgy parts Supporting category Parts name: automobile engine; camshaft, crankshaft timing pulley, water pump, oil pump pulley, driving and driven gear, driving and driven sprocket, cam, bearing cover, rocker arm, Bushings, thrust plates, valve guides, intake and exhaust valve seats, automotive gearboxes, etc.

What defects will powder metallurgy gears cause during the compaction process? Shape and position tolerance out of tolerance: 1. Straightness: The reasons for straightness out of tolerance include: out of mold straightness, uneven density distribution of green body, uneven wall thickness of green body, etc. 2. Parallelism: The reasons for an out-of-tolerance parallelism include: out-of-tolerance parallelism of the mold, uneven powder filling, etc. 3 Coaxiality: The reasons for the difference in coaxiality are: the precision of the mold is too low, the precision of pressing tools and equipment is low, the installation of the mold does not meet the requirements, and the dress is not uniform. When the powder flow rate is appropriate, the mold accuracy meets the design requirements, and the pressing tooling and equipment accuracy meet the installation requirements, the shape and position tolerance is mainly related to the density distribution of the compact. When the pressing method is determined, the density distribution of the compact is directly related to the powder filling effect. . Unqualified appearance: high roughness, excessive burr data, dropped edges and corners, roughness and cracks are all common design defects of compacts. Post-treatment of powder metallurgy gears: carburizing treatment, carbonitriding, quenching integrated treatment, the hardness range is relatively high.
